Daniele Duella and Iango Henzi/WAlthough Beyonce and Christina Aguilera have dueling W magazine covers for the month of July, it's Xtina who literally bares all in the publication, which hits newsstands June 21. Not only does the 30-year-old singer pose rather provocatively for the spread, but she opens up about the incredibly rough year she's had, which included canceling a concert tour due to low ticket sales, getting divorced from music producer Jordan Bratman, flubbing the lyrics to the "Star-Spangled Banner" at the Super Bowl, and being arrested with her current boyfriend Matt Rutler for being "extremely intoxicated."

Beyonce: Fierce, Fearless, Female 

"I don't mean to martyr myself, but I think I was a victim of celebrity," Aguilera tells the mag of the incident. "I don't drive, I wasn't driving, and I committed no crimes, but they put me in jail. They called me a 'political hot potato.' They said, 'What are we going to do with this woman?' I think they were bored that night."

The youngest star on our list is Justin Bieber. In his meteoric rise to fame, the 17-year-old crooner skipped the dues-paying drudgery of touring clubs and small venues that many artists go through to work their way up. Instead, at a time when most teens are worrying about who to invite to prom, he's been touring the world and starring in a hit concert documentary. Bieber ranks second on our list with $53 million in earnings over the past 12 months. That money,

Jennifer Hudson had two morning show appearances scheduled on Friday to promote her latest album, I Remember Me. Unfortunately, she became ill after performing on ABC's "Good Morning America" and never made it to the CBS "Early Show." According to her rep, Hudson "went to the hospital due to severe abdominal pains" and "was treated for food poisoning and released."

Fortunately, all of the 29-year-old singer's fans who gathered in NYC's Central Park for the "GMA" appearance still got treated to a mini-concert by the "American Idol" alum, who looked absolutely fabulous in a flowing white top and high-waisted black mini skirt.

Jennifer -- who has shed a whopping 80 pounds -- also chatted with hosts Robin Roberts and Lara Spencer to discuss her upcoming movies ("Winnie," "The Three Stooges") and memoir, which she hopes will "inspire others in their weight loss journey."

She also answered a few quickfire questions such as ....

What's she addicted to? "Chocolate."

Gwen Stefani apparently doesn't want to fly solo on stage any longer. - Francois Durand/Getty ImagesShe prefers rocking out with her bandmate (and former boyfriend) Tony Kanal. - Jun Sato/WireImage.comGwen Stefani continues to be photographed everywhere she goes -- usually with hubby Gavin Rossdale and their two adorable tots, Kingston and Zuma -- but we haven't heard a whole lot from her musically in a while. It's been five years since she released her last solo effort, The Sweet Escape, and 10 years since No Doubt's last album, Rock Steady. But not to worry ... in the new issue of Entertainment Weekly (on newsstands Friday), Gwen and the boys of No Doubt, including guitarist Tom Dumont, bassist Tony Kanal, and drummer Adrian Young, reveal their future plans for the band. (Hmmm ... sounds like someone might be dropping a new album or going on tour!) As for the "Hollaback Girl's" solo careeer, that's another story. Gwen is apparently calling it quits.

"That was a moment in time," she tells EW. "It went on a little longer than we all thought it would because it was inspired and you have to go with wherever you're at in that time in your life ... [but] everything works out how it

Country queens Shania Twain and Taylor Swift channeled one of the most famous duos in film history -- the lead characters in 1991's "Thelma and Louise" -- on Monday. No, the two weren't really on a road trip to escape the police ... although that would make for one crazy story! They were filming a parody video to kick off Wednesday's 2011 CMT Music Awards at Nashville's Bridgestone Arena.

Wearing big sunglasses while cruising in a vintage blue convertible, the singers portrayed the roles made famous by Susan Sarandon and Geena Davis. "Glee's" Chord Overstreet also joined them on the video's set in Thompson's Station, Tennessee. Perhaps he played the part that once belonged to a little-known actor named Brad Pitt?

The reenactment comes on the heels of the movie's 20th anniversary. On Monday, Sarandon and Davis even made an appearance at Toronto's TIFF Bell Lightbox for a special screening of the film to raise money for the Women's College Hospital Foundation, a charity that supports

Although Kelly Rowland hasn't necessarily achieved the level of fame that fellow Destiny's Child singer Beyonce Knowles has, she's still managed to keep herself in the spotlight. She currently serves as a judge on the U.K. edition of "X Factor," and her hit single "Motivation" (featuring Lil Wayne) hit #1 on the Billboard R&B/Hip-Hop charts, and climbed to #21 on the Hot 100. That's probably why the 30-year-old singer is so excited about the rest of her album -- appropriately entitled Here I Am -- which is set to drop this fall. When asked about the title, Kelly laughed, "I want people to know I'm here. This is the record I've been working for forever." Check out the rest of her interview with "Access Hollywood" to get the dish on Here I Am. Looks like her solo star is on the rise!

Elton John has received many accolades over the years. He has six Grammys, was inducted into the Rock and Roll Hall of Fame in 1994, and has even been knighted by HM Queen Elizabeth II for his "services to music and charitable services." Now, the "Rocket Man" singer and his partner, David Furnish, have been nominated to win the Celebrity Dads of the Year award -- in England that is. The first-time fathers welcomed their son, Zachary, into the world last Christmas thanks to the help of a surrogate mother, and are reportedly "thrilled" that they're in the running for the special honor.

Elton, 63, has said that although he is incredibly famous, he wants Zachary to have a normal upbringing. "I so value my own childhood now, and we want to give Zachary -- as much as we

Say what you will about Lady Gaga, but she certainly knows how to put on the show! The pop star -- who is busy promoting her new album, Born This Way -- kicked off "Good Morning America's" Summer Concert Series with a performance in Central Park Friday morning. Thousands of Gaga's "Little Monsters" gathered -- some who began camping out for three days before the concert! -- and watched as the "Poker Face" singer ziplined her way to the stage.

After opening the show with "Bad Romance," Gaga sat down for a chat with "GMA's" Robin Roberts and George Stephanopoulos. "I love my fans," Gaga said. "They're my family, for sure. It's an absolute dream to play here in Central Park. I grew up five blocks from here. And just to see this many people here to listen to my music makes me feel so blessed."

The singer went on to perform four more tunes from her new album, including "Born This Way," which she says is about "being yourself and loving who you are and being proud," "Judas," "Hair," and
